makeChrStrandData-methods: Map a data matrix onto chromosome coordinates

In ChromHeatMap: Heat map plotting by genome coordinate

Description

Given a data matrix with row names corresponding to the probe or gene IDs in an accompanying annotation package, returns a data structure that can be used with the plotChrMap function. Based on the Makesense method from the geneplotter package.

Methods

expr = "ExpressionSet"

Given an ExpressionSet object, returns a ChrStrandData object.

expr = "matrix"

Given a matrix object (where rownames(expr) yields the probe or gene identifiers used by the annotation package), returns a ChrStrandData object.
